When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. Input values should be added to the list until -1 is entered. Ex: If the input is:

5.23 LAB: Adjust values in a list by normalizing When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65 The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0. Use Python, please.
6.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique. END WITH A NEW LINE
13.14 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in ArrayList class (ArrayListLibrary arrayListLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and ArrayListLibrary insertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each insertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of ArrayList operations: 1 Which list do you think will require the most operations? Why?

22.3 LAB: Remove all even numbers from a list (Use Python) Write the remove_evens() function, which receives a list of integers as a parameter and returns a new list of integers containing only the odd numbers from the original list. The main program outputs values of the returned list. Hint: If the original list has even numbers, then the new list will be smaller in length than the original list and should have no blank elements. Ex: If the list passed to the remove_evens() function is [1, 2, 3, 4, 5, 6, 7, 8, 9], then the function returns and the program output is: [1, 3, 5, 7, 9] Ex: If the list passed to the remove_evens() function is [1, 9, 3], then the function returns and the program output is: [1, 9, 3]
6.44 LAB: Contact list (JAVA) A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program in java that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) Hint: Use two arrays: One for…
6.19 LAB: Replacement words Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique. The code I have is this but I can't find out how to make a new line.. #Define main() function def main(): #Read data from the user replace_pairs = input() #Split replacement pairs into list replace_pairs = replace_pairs.split() #Create two lists for original and replacement words originalWord = [] replacementWord = [] #Iterate through replacement pairs for i in range(len(replace_pairs)): #If it is even place if i % 2 == 0:…
11.17 (Bucket Sort) Use Python. Show the whole code input and output when done. A bucket sort begins with a one-dimensional array of positive integers to be sorted and a two-dimensional array of integers with rows indexed from 0 to 9 and columns indexed from 0 to n – 1, where n is the number of values to be sorted. Each row of the two-dimensional array is referred to as a bucket. Write a class named BucketSort containing a function called sort that operates as follows: a) Place each value of the one-dimensional array into a row of the bucket array, based on the value’s “ones” (rightmost) digit. For example, 97 is placed in row 7, 3 is placed in row 3, and 100 is placed in row 0. This procedure is called a distribution pass. b) Loop through the bucket array row by row, and copy the values back to the original array. This procedure is called a gathering pass. The new order of the preceding values in the one-dimensional array is 100, 3 and 97. c) Repeat this process for each subsequent…
3.6.5: Printing array elements separated by commas. Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline.
5.23 C++ Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once. For coding simplicity, follow each output word by a comma, even the last one. Add a newline to the end of the last output. Assume at least one word in the list will contain the given character. Ex: If the input is: 4 hello zoo sleep drizzle z then the output is: zoo,drizzle, To achieve the above, first read the list into a vector. Keep in mind that the character 'a' is not equal to the character 'A'.
8.19 (Removing a Particular Word From a Given Line of Text) Write a program that inputs a line of text and a given word. The program should use string library functions strcmp and strcpy to remove all occurrences of the given word from the input line of text. The program should also count the number of words in the given line of text before and after removing the given word using the strtok function. Solve it Without using pointers
8.26 LAB: Word frequencies (dictionaries) Implement the build_dictionary() function to build a word frequency dictionary from a list of words. Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1} Ex: If the words list is: ["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"] the dictionary returned from calling build_dictionary(words) is: {'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1} The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value. Ex: If the input is: hey hi Mark hi mark the output is: Mark: 1 hey: 1 hi: 2 mark: 1 Use Python, please.
